Speaking of future disk expansions.  It might be smart move to place all 
file systems (or at least /var/spool/imap) under LVM.  That way he can 
simply add new disks into volume group, assign additional space to 
logical volume where /var/spool/imap file system resides, and resize 
file system to the new size of logical volume.  The only downtime would 
be to physically attach new disk(s).  Everything after that can be 
performed while the system is up and running (and users are using it).
